Rose plant named ‘Empintoimp’

ABSTRACT

A new and distinct cultivar of Rose plant named ‘Empintoimp’, characterized by its long and upright flowering stems; strong plants; dark red-colored flowers; and excellent postproduction longevity.

Botanical designation: Rosa hybrida.

Cultivar denomination: ‘Empintoimp’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Roseplant, botanically known as Rosa hybrida, commercially used as a cutflower Rose, and hereinafter referred to by the name ‘Empintoimp’.

The new Rose plant is a product of a planned breeding program conductedby the Inventor in Aalsmeer, The Netherlands. The objective of thebreeding program was to develop new freely-flowering cut flower Rosevarieties with attractive flower colors and excellent postproductionlongevity.

The new Rose plant is a naturally-occurring whole plant mutation of Rosahybrida ‘Empinto’, not patented. The new Rose was discovered andselected by the Inventor as a single flowering plant from within apopulation of plants of ‘Empinto’ in a controlled greenhouse environmentin Aalsmeer, The Netherlands in 2008.

Asexual reproduction of the new Rose by cuttings at Aalsmeer, TheNetherlands, has shown that the unique features of this new Rose plantare stable and reproduced true to type in successive generations ofasexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Empintoimp’. These characteristics incombination distinguish ‘Empintoimp’ as a new and distinct Rosecultivar:

-   -   1. Long and upright flowering stems.    -   2. Glossy dark green-colored leaves.    -   3. Dark red yellow-colored flowers.    -   4. Excellent postproduction longevity.    -   5. Resistant to Powdery Mildew.

Plants of the new Rose differ from plants of the parent, ‘Empinto’,primarily in flower bud size as plant of the new Rose have tallerflowers buds than plants of ‘Empinto’.

Plants of the new Rose can be compared to plants of Rosa hybrida‘Freedom’, not patented. In side-by-side comparisons conducted inAalsmeer, The Netherlands, plants of the new Rose differed from plantsof ‘Freedom’ in the following characteristics:

-   -   1. Plants of the new Rose had glossier leaves than plants of        ‘Freedom’.    -   2. Outer flower petals of plants of the new Rose did not bronze        or blacken whereas outer flower petals of plants of ‘Freedom’        bronzed and blackened.    -   3. Plants of the new Rose were resistant to Downy and Powdery        Mildew whereas plants of ‘Freedom’ were not resistant to Downy        and Powdery Mildew.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearanceof the new Rose plant, showing the colors as true as it is reasonablypossible to obtain in colored reproductions of this type. Colors in thephotograph may differ slightly from the color values cited in thedetailed botanical description which accurately describe the colors ofthe new Rose.

The photograph comprises a side perspective view of typical floweringstems of ‘Empintoimp’.

DETAILED BOTANICAL DESCRIPTION

Plants of the new Rose have not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature and light intensity,without, however, any variance in genotype. The aforementionedphotographs, following observations and measurements describe plantsgrown during the summer and early autumn in Aalsmeer, The Netherlands,in a glass-covered greenhouse and under commercial production practices.Plants had been growing for ten months when the photographs anddescription were taken. During the production of the plants, daytemperatures averaged 20° C., night temperatures averaged 18° C. andlight levels averaged 10 kilolux. In the following description, colorreferences are made to The Royal Horticultural Society Colour Chart,2001 Edition, except where general terms of ordinary dictionarysignificance are used.
